Paratesticular aggressive fibromatosis: CT findings

Abstract

Aggressive fibromatoses commonly originate from the musculoskeletal system, mesentery, and retroperitoneum. We report a case of aggressive fibromatosis arising from the spermatic cord. On helical computed tomography, the lesion appeared as a solid mass with well-defined borders in the scrotum and with infiltrative features in the retroperitoneum.

Scrotal Lymphangioma

“…12 Unusual scrotal masses that have been reported include schwannoma, 13 simple epidermoid cyst, 14 ectopic pheochromocytoma, 15 and aggressive fibromatosis. 16 Lymphangiomas are very rare scrotal masses of which, to our knowledge, sonographic images have not been reported in the radiologic or sonographic literature.…”

Paratesticular fibromatosis: A rare cause of testicular mass

“…4 On imaging the mass extended into the retroperitoneum along the testicular artery. 4 This aggressive tumour invaded the bladder, sigmoid colon, left ureter and left external iliac vessels and was subsequently incompletely excised with margins at the left external iliac vessels and left ureter. 4 Similar to the case described in this review, the tumour was a solid and firm with a white surface; however, it was aggressive in nature.…”

Aggressive Fibromatosis in the Urological System

“…Gluck et al [8] and Lai et al [9] reported 1 case each of AF arising primarily from the spermatic cord in 1987 and 1995 respectively. Sumi et al [10] described a case whose lesion originated from the spermatic cord and extended to the retroperitoneum through the internal inguinal ring. The mass invaded the bladder, the sigmoid colon, the left ureter, and the left external iliac vessels.…”

“…To our knowledge, only 3 cases of AF arising from the paratesticular structures have been described [8][9][10] ( table 1 ). Gluck et al [8] and Lai et al [9] reported 1 case each of AF arising primarily from the spermatic cord in 1987 and 1995 respectively.…”

“…In our review of the literature, most series are very small and anecdotal [4][5][6][7][8][9][10] . As shown in table 1 , only 4 such cases of bladder tumors have been reported since 1975.…”
